Bp Not Decreasing With 100mg Losartan

Hi I’ve been taking 50mg losartan for almost a year and BP was avg 128/89 then it went up to 140/100. My Dr upped it to 100mg and after a week it went up a little more. How long does it take for the medicine to start working and should it start working sooner since I’ve been taking losartan previously?

@SW,

You mentioned that you've been taking 50mg losartan for almost a year before it stopped working as effectively... I'm just under the unique impression that perhaps your body built a tolerance to it over time and that's why your blood pressure was gradually going back up? I've never heard of any medication taking a year to start working, so this is the only plausible explanation I can think of. Have you already discussed this with your prescribing doctor? I'm curious to know if he'd recommend trying something different to help balance out your body's tolerance...

Has anyone else had this happen?

I started out on 25mg then to 50 now 100 losartan. We talked about other meds but didn’t start yet. Could it be that losartan isn’t right for me?
